In April 2026, Microsoft disclosed and patched a critical remote code execution vulnerability affecting the Windows Internet Key Exchange Service Extensions. Tracked as CVE-2026-33824, the issue was addressed as part of Microsoft’s April 2026 Patch Tuesday release. The affected component forms part of the Windows IPsec and IKEv2 stack, which is widely used to provide secure network connectivity.

CVE-2026-32201 is a spoofing vulnerability in Microsoft SharePoint Server stemming from improper input validation. It permits an unauthenticated remote attacker to spoof trusted content and resources over the network. The flaw affects on-premises deployments of SharePoint Server 2016, 2019, and Subscription Edition. Exploitation has been observed in the wild as a zero-day prior to the April 2026 Patch Tuesday release.

CVE-2026-23869 is a denial of service vulnerability in React Server Components, caused by improper handling of cyclic data structures during deserialization of incoming HTTP requests. The vulnerability resides in the React Flight protocol's server-side reply handling, specifically in the createMap, createSet, and extractIterator functions within ReactFlightReplyServer.js. The vulnerability carries a CVSS v3.1 base score of 7.5 (High). Exploitation requires no authentication and no user interaction.

CVE-2026-21643 is a critical SQL injection vulnerability in the administrative web interface of FortiClient Endpoint Management Server version 7.4.4. It allows unauthenticated remote attackers to execute arbitrary SQL commands through specially crafted HTTP requests, primarily by injecting malicious payloads via the Site HTTP header.

Anthropic’s Project Glasswing and the Claude Mythos model represents a fundamental change in the physics of cyber defense. With the gap between patch releases and weaponized exploits shrinking to hours, traditional manual security triage is now obsolete. Organizations must adopt AI-driven automated remediation.

It’s been a chaotic few weeks for Axios. First, a major supply chain attack put the package under scrutiny. Then, just days later, headlines started appearing about a “critical 10/10 vulnerability” that could lead to full cloud compromise. If you’ve read the coverage, you’ve probably seen claims like: That sounds bad. But when you look closely at how this vulnerability actually behaves in real environments, the story changes.

A few weeks ago the world was exposed to Mythos, Anthropic's new frontier model and the Project Glasswing announcement that came with it. The reaction across the industry was immediate. Cybersecurity stocks fell sharply. The Treasury Secretary convened an emergency meeting with major bank CEOs. 250 CISOs produced a response playbook over a single weekend. That is not a typical announcement or a PR "leak". That is a reckoning. Then, about a week later, I came across MOAK.

Building a supply chain security company comes with an uncomfortable truth: our remediated packages run inside our customers' production environments. A compromise on our end is a compromise on theirs. We take that responsibility seriously. I want to pull back the curtain on how we actually secure our own supply chain - from the code we write, to the artifacts we deliver, to the infrastructure that holds it all together. ‍

What the Anthropic Mythos findings mean for every security team, and the 90-day window you cannot afford to miss. Last week, Anthropic published something that should stop every CISO in their tracks. Its Mythos Preview model, running autonomously, without expert guidance, identified thousands of high- and critical-severity vulnerabilities across major operating systems, browsers, and open-source projects.
